Mesh network has the advantages of self-organization, self-healing, self-management, high stability and security. It is fast, convenient and covers a wide range. This paper takes the mesh ad-hoc network technology as the main research content, and expounds the necessity of building a mobile communication platform in power grid dispatching. Taking a power grid ADNOC project as an example, this paper introduces the process of establishing and using the mesh network in detail. A trusted routing scheme based on trusted computing and assisted by trust mechanism is proposed, and the specific problems involved in it are analyzed and studied.
